Characteristics of Salivary Gland Tumors
- Adenoid Cystic Carcinoma: characterized by perineural spread
- Benign salivary neoplasms: common symptom is painless, slowly growing swelling in the parotid region
- Benign salivary neoplasms on palpation: well-defined and firm in consistency
- Adenolymphoma: soft or cystic in consistency
Types of Tumors
- Acinic Cell Carcinoma: arises from the acinic cells of the parotid gland
- Mucoepidermoid Carcinoma: a type of malignant tumor that can arise in the salivary glands
- Warthin's Tumor: a type of tumor that can arise in the salivary glands
- Pleomorphic Adenoma: not a type of malignant tumor
Clinical Features

- Adenoid Cystic Carcinoma: possible complication is distant metastases
Examination of the Mouth Cavity
- Important feature to note: tumors arising in the deeper part of the parotid may bulge in the oropharynx
- Differential diagnosis for a swelling in the oropharynx: Carotid body tumor
